Can't change title

[dnish]

Hey, I'm having an issue when I try to change the title of the header. For example my app component looks like this:

class App extends Component {

    constructor(props) {
        super(props);
        this.state = {
            headerName:'Erster Aufruf'
        };
    }






    componentDidMount() {
        setTimeout(() => {
            this.setState({headerName:'New title'});
        },5000);


    }


    componentWillUpdate() {
        alert('Will update');
    }
    render() {

        return (

        <Router
            firstRoute={{

            component:Dashboard,
            headerStyle: {backgroundColor: '#48cfad'},
            name:this.state.headerName
            }}
        />
        );
    }
}

After changing the state, componentWillUpdate fires but the title in the header still remains the same.

Even if I add an own Title component and try to set the props via this.props.setTitleProps, nothing changes.

At this time, we can't easily update the title of the current route.

PRs are welcome :)

Yeah, I am using an own title component. This works without problems :)

[charpeni]

Can you share with us how you do that for further question? :)

[dnish]

Yeah, I'll post tomorrow the code here. In my case I am using a ScrollView slider and change the title if I've slided to the next component.

Oh cool.

Related to #122.

Here's my answer:

index.js

     <View style={{flex:1}}>
            <Router
                firstRoute={{
                component:Dashboard,
                titleComponent:Title}}

            />

        </View>

title.js

export class Title extends React.Component {

constructor(props) {
    super(props);
}




render() {
    return (<View><Text>{this.props.name}</Text></View>);
 }
}

dashboard.js

export class Dashboard extends React.Component {

   constructor(props) {
    super(props);
  }


  componentDidMount() {

    //Here we change/set the title
    this.props.setTitleProps({name:'Latest post'});

 }


 render() {
   <View>...</View>
  }


}

So in this case we can easily set the title via property and change it whenever we want.
